And getting taller as you age, we also learn Mount Everest is growing.

Plus, did you know soil has a sound?

If I stuck my microphone into the dirt, it might sound something like this.

Thank you for being with us on this last day of 2024.

Saying goodbye to one very eventful year and getting ready to say hello to a new one.
